This mattress is not soft . I repeat it is nor soft.
Poster Michael is intentionally misleading. Buyer beware. It was only 8 inch not 9 inch.

Prior to this I purchased a different latex mattress. Due to wool and cotton batting in that mattress, it developed a body impression in just a few days. Back it went.

Which is what I love about this mattress: It has hardly any padding on top of the latex. Just a very thin layer of wool and a nice organic knit cover over that. Nothing to compress, nothing to bunch up, nothing to create an uneven sleeping surface. If you'd like a little padding, you can put a 1 or 2" wool topper on top of it, or whatever. IMO, this is a much better solution than having these materials built-in where you cannot tailor them to your own preference. This way you can add, remove or replace them as desired. Personally, I like it as is.

The only way this mattress is going to sag is if you don't have a proper foundation underneath it.

I purchased this mattress as a last-ditch effort before going with FloBeds. It was cheaper, and zero risk because if I didn't like it, Sam's Club would simply come and pick it up and refund my money.

It is a firm mattress, which I ascertained by examining its published Dunlop latex ILDs and doing a modicum of due diligence. If you aren't seeking a firm latex mattress, look elsewhere. If you are, you have absolutely nothing to lose by trying this out. It is very well made and I've been incredibly happy with it -- and am considering purchasing two more.

My low back pain has increased by sleeping on this mattress! On a scale of 1-10, I had 4 now I have 8-9 low back pain, all due to sleeping on this Sams Club organic latex mattress which is made by Innomax as white night.

I repeat do not buy this mattress. I have suffered long enough and am returning it.
